          Abstract

          En el presente trabajo se realiza un estudio del efecto del endurecimiento por deformación en el comportamiento del desgaste por fricción seca del acero inoxidable austenítico AISI 304. El comportamiento de la microestructura martensítica del acero inoxidable AISI 420 se usó como patrón de comparación con la microestructura austenítica. Las dos microestructuras fueron sometidas a tres diferentes cargas durante cinco diferentes tiempos de contacto y a una velocidad de giro constante. El desgaste en las muestras tipo disco de cada una de las microestructuras fue determinado por medio de la pérdida de peso. El análisis de los resultados, basándose en la pérdida de peso de los materiales ensayados y el cambio de la microdureza ocurrido en la microestructura austenítica, señalan que el efecto del endurecimiento contribuye a mejorar su resistencia al desgaste.

          The effect of strain hardening on the behavior of austenitic stainless steel AISI 304 under dry friction wear, has been studied. The martensitic microstructure behavior of stainless steel AISI 420 has been used as a comparative pattern with austenitic microstructure. Both microstructures were subjected to three different loads during five different contact times and to a constant turn speed. The wear in the sample type disks of each one of the microstructures was determined by means of the weight lost. Tests result analysis based on weight lost and the hardness changes on austenitic microstructure show that strain hardening effect improves the wear strength of this microstructure.
